Pure cortical supratentorial extraventricular ependymoma.
Majority of ependymomas are infratentorial and intraventricular. Supratentorial and purely cortical extraventricular ependymomas are extremely rare and only five cases were reported. We report a 15-year-old male with left frontal cortical ependymoma. He had gross total excision of the lesion and was not given radioptherapy.
متن کاملSupratentorial Extraventricular Anaplastic Ependymoma Presenting with Repeated Intratumoral Hemorrhage
Supratentorial extraventricular anaplastic ependymomas are extremely rare. We report the case of a 23-year-old male with a supratentorial extraventricular anaplastic ependymoma that presented with repeated intratumoral hemorrhage. The patient was diagnosed with an intracerebral hematoma in the left occipital lobe and underwent operation. The hematoma did not reveal tumor cells, but a new tumor ...
متن کاملRecurrent paediatric supratentorial extraventricular ependymoma associated with genetic mutation at exon 4 of p53 gene.
Recurrent supratentorial extraventricular ependymoma in a four-year-old Malay boy treated twice surgically in combination with cranial radiotherapy is reported. He presented with symptoms of raised intracranial pressure and a history of focal seizure. Computed tomography of the brain showed a left supratentorial extraventricular cystic lesion causing a mass effect. The tumour histology was epen...
متن کاملPatterns of brain infiltration and secondary structure formation in supratentorial ependymal tumors.
Ependymomas are generally considered to be noninfiltrative tumors that have discrete borders with adjacent brain tissue. Most occur in the posterior fossa or spinal cord. Supratentorial ependymal tumors arise near the ventricular system or, more rarely, within the cerebral white matter or cortex. Presented here are 6 supratentorial ependymal tumors, 3 that primarily involve the cerebral cortex ...
متن کاملSupratentorial intracerebral epithelial (ependymal) cysts: review, case reports, and fine structure.
The paper concerns the rare supratentorial, intracerebral or convexity cysts in adults having a wall lined with an epithelium resembling ependyma. The clincopathological aspects of such cysts are reviewed from 15 published cases and two specimens of the authors which could be examined with the electronmicroscope. These cysts manifest at a median age of 46 years as progressive, space occupying l...
